Perovskite solar cells (PSC) have emerged in the past decade as an exciting, low-cost, renewable-energy technology, and the efficiency with which they convert sunlight to electricity is now on par with silicon solar cells. However, the health and environmental impacts of the solvents involved in PSC processing remain a barrier for commercialization and large-scale production. The solvents, some of which are very hazardous, may be released into the atmosphere causing environmental and health impacts, condensed for energy recovery via incineration, which produces carbon emissions, or distilled for solvent recovery, which requires additional infrastructure and energy input. This project will focus on sustainable chemistry and engineering of PSCs via green-solvent and solvent-free approaches. Notably, this project will take an integrated, multidisciplinary approach that considers all key components of a PSC; the light-absorbing perovskite layer, charge-transport layers, and performance-enhancing additives. A novel insitu-transmission characterization technique will be used to provide fundamental insight into the formation of the PSC layers with green solvents. The manufacturing processes will be studied and optimized to minimize harmful solvents and exhaust, and the performance of the PSCs will be studied and collaboratively optimized by the Canadian and German teams to achieve sustainable PSC manufacturing.

钙钛矿型太阳能电池(PSC)是过去十年中出现的一种令人兴奋的、低成本的可再生能源技术，它们将阳光转化为电能的效率现在与硅太阳能电池不相上下。然而，PSC加工所涉及的溶剂对健康和环境的影响仍然是商业化和大规模生产的障碍。这些溶剂，其中一些是非常危险的，可能被释放到大气中，造成环境和健康影响，通过焚烧进行冷凝以回收能源，这会产生碳排放，或者蒸馏用于溶剂回收，这需要额外的基础设施和能源投入。该项目将侧重于通过绿色溶剂和无溶剂方法实现PSCs的可持续化学和工程。值得注意的是，该项目将采取综合的、多学科的方法，考虑PSC的所有关键组件：吸收光的钙钛矿层、电荷传输层和增强性能的添加剂。一种新的原位透射表征技术将被用来提供对绿色溶剂形成PSC层的基本见解。将研究和优化制造工艺，以最大限度地减少有害溶剂和废气，加拿大和德国团队将研究和合作优化PSC的性能，以实现可持续的PSC制造。
